City of Morgan Hill
Water System Master Plan
water demand factor is approximately 15.2 mgd. The existing firm supply capacity is
approximately 17.2 mgd, which results in a supply surplus of 2.0 mgd.
7.5.2
Future Supply Requirements
Future supply requirements, in 5-year increments, were identified for the City and are also
summarized on
Table 7.1
. As shown on
Table 7.1
the City’s existing firm supply capacity is
sufficient to meet the City’s future supply requirement until the year 2030, at which point the
supply requirement exceeds the City’s existing firm supply capacity and a new well is required to
be constructed. Following the construction of this new well the City will not need to construct a
new well to meet the future supply requirement until the year 2030, when the future supply
requirement will exceed the City’s future firm supply capacity. The proposed groundwater wells
are described as follows:
BR-W1:
Construct a new 800 gpm groundwater well on Burnett Avenue. This facility will
be located approximately 6,000 feet northeast of Monterey Avenue.
NH-W1:
Construct a new 800 gpm groundwater well on Butterfield Avenue. This facility will
be located approximately 400 feet northeast of the intersection of Railroad Avenue and
Fisher Avenue.
7.6 WATER STORAGE REQUIREMENTS
The City’s existing domestic water system storage capacity is identified in this section.
Additionally, this section identifies the existing and future storage requirements to meet the
storage capacity and compares it with the existing storage facilities in each zone and makes
recommendations for new storage facilities.
7.6.1
Existing Storage Requirements
Existing storage requirements were identified for each pressure zone and are summarized in
Table 7.2
. The table lists the existing domestic water demands and identifies the operation, fire,
and emergency storage for each pressure zone. This table also lists the total required storage for
existing domestic water demands at 8.7 MG.
7.6.2
Future Storage Requirements
Future storage requirements were identified based on the buildout of the 2035 General Plan and
summarized by pressure zone on
Table 7.3
. The table lists the future domestic water demands
and identifies the operations, fire, and emergency storage for each pressure zones. The table also
lists the total required storage for future domestic water demands at 6.0 MG.
7.6.3
Recommended New Storage Facilities
The existing and future storage requirements, shown on
Tables 7.2
and
T
able 7.3
, were
compared with existing City storage facilities in each pressure zone and the required storage
